Description

This special Tungsten Lanthanum Oxide (WL) was specifically developed for use in the stems (support rods) of high-pressure discharge lamps. A special production process is used to create a more fine-grained microstructure than is found in standard quality tungsten-lanthanum oxide. Thanks to this special microstructure, the breaking strength of the material is higher than that of standard quality WL and WVM even following exposure to high thermal loads.

This material data has been provided by Plansee.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
